。 Equipped with a driving pulley and a driven pulley around which a V-belt is wrapped, each pulley has a fixed sheave that cannot move in the axial direction and a movable sheave that can move in the axial direction, and the transmission is transmitted to the movable sheave of one of the pulleys. In a V-belt continuously variable transmission equipped with a torque cam device that generates thrust according to torque, the torque cam device has a cam surface and a cam roller that rolls on the cam surface, and the cam surface is movable. It is formed as a cam member that is separate from the sheave and rotatably attached to the back of the movable sheave, and a sleeve that is slidable on the shaft and supports the inner diameter of the movable sheave is fixed to the fixed sheave. A torque cam device for a V-belt continuously variable transmission, characterized in that a ball spline for guiding a movable sheave only in the axial direction is provided between the outer circumference of the sleeve and the inner circumference of the cam member.
